| 摘 要： | 针对Y型明渠交汇口的水流特性,应用水深平均-雷诺应力模型,采用交错网格有限体积法离散控制方程以及SIMPLE算法,求解交汇水流的水深-速度场.数值计算结果与物理模型试验结果吻合较好,并据此分析了交汇口附近汇流区的雷诺正应力和剪切应力分布.

| Abstract: | Considering characteristics of the flow at Y-shaped open-channel junction,the finite volume method on staggered grids is used in a depth-averaged Reynolds stress model to discrete the control equations and SIMPLE algorithm so as to obtain the depth-velocity fields.Numerical calculation results agree well with the physical model test results,and distributions of the Reynolds normal stress and shear stress around the junction are analyzed. |

| Keywords: | Reynolds stress model junction separation zone Y-shaped open-channel numerical simulation |
